To aZZ whom it may concern.-

lle it known that l, LOGAN MOKNIGHD BU L- Li'r'r, a citizen of theUnited States, residing at St. .llauhin the county of Ramseyfitate ofMinnesota, have invented certain new and useful Improvements inGanWhecls, of which I do declare the following to be a full, clear, andexact description, reference being bad to the accompanying drawings,forming part of this specification.

My present invention has relation to carwhecls designed to rotate freelyupon their axles, and partieularl y does it relate to the improvement oithat class oisuch wheels wherein provision is made for the lubricationof the journals without the necessity for the employment of separatejournal-boxes.

The object of my invention is to provide a simple, durable, andeffective means whereby a thorough li'ibrication of the journals may besecured; and to this end my invention consists in the various novelfeatures of construction, hereinafter described, illustrated in the arecompanying drawings, and particularly defined in the claims at the endof this specification.

Figure 1 is a view in side elevation of a car-wheel having myimprovements applied thereto. Fig. 2 is a view in vertical crosssectionon line :r as of Fig. 1. Fig. 3 is a detail view, in side elevation, ofthe hub of my improved wheel. Fig. l is a view in vertical sectionthrough the hub at a point immediately adjacent its central web.

lily present invention is showii as applied to a car-Wheel, the bed y ofwhich is composed of two sets or series of wooden segments, A, the innerends of which bear against the periphery ol the hub B, and are thereheld in the annular grooves formed by the flanges I; and theintermediate web, h',while their outer ends are connected with the tireGof the wheel by means of the rctaining-ring D, the ring or fillet 1*],and the through-bolts P, which latter pass through the retaining-ring,the fillet, and the outer ends of the segments, and hold these partssecurely to the depending flange c of the tire. It will be understood,however, that while I have shown In y invention as applied to acar-wheel having a wooden body constructcd and connected with the huband periphery in the manner above defined, and while the invention isparticularly suited to this kind of wheel, I. do not wish my inventionto be understood restricted to such form of wheels, since it isapplicable, also, to carwheels of various other constructions.

The central portion of the hub B of the wheel consists of an annularbeariugplate, b, which, together with the end plates, b and Z1, and theperiphery of the hub, form a closed annular chamber, G, adapted toreceive a quan tity of suitable lubricant. Across this annular chamber Gextend the division-plates g, having openings 9 therein communicatingwith the main portion of the annular chamber G, and through the annularbearing-plate b" of the hub, at a point between the divisionplatcs g, isformed a delivery duct or channel, If, through which the lubricant willpass to the journal of the caraxle. My purpose in thus providing theannular chamber G with the division-plate gis to form a receptacle, G,for cotton waste or like material, through which the oil or otherlubricant will gradually filter before passing through the delivery-ductIf to the face of the journal. It will be seen that by thus providing areceptacle for .the cotton waste at a point opposite the delivery duet bit will be in thebest position for delivering the lubricant to thejournal, and as this receptacle G, wherein the cotton waste is retained, communicates through the openings in the division-plates withthe main body of the chamber G the cotton waste will be saturated withthe lubricant so lon there is any within the annular chamber, and whilepreventing the too free escape thereof will insure its proper deliveryto the journal. Through the end wall, 12*, of the hub B there arepreferably formed two openings, fitted, respectively, with thescrew-threaded caps H and H, one of these openings communicating withthe annular chamber G, and serving to admit the lubricant thereinto,while the other opening communicates with the receptacle G for thepurpose of permitting the introduction of cotton waste to suchreceptacle.

From the foregoing description it will be seen that when the receptacleG" has been suit- KOO ably filled with cotton Waste or like material,and the lubricant has been introduced into the annular chamber G, thecotton waste will speedily become saturated with the lubricant, whichwill gradually pass thence through the delivery-duct 1) onto thewearing-face of the journal. By thus forming the hub B with a chamberfor lubricant about its annular bearingplate, and by forming the wallsof such chamber integral with the annular bearing and periphery of thehub, I am enabled to produce an effective means of supplying lubricantto the journal, and this, too, without increasing to any considerableextent the cost of the wheel. Moreover, it is apparent that byconstructing the walls of the chambers G and G as integral parts of thehub I avoid all danger of the leakage of the lubricant, which would beliable to occur in case the sides of such chamber were formed separatefrom the hub and attached thereto by bolts.

While I have illustrated in the accompany ing drawings what I regard asthe preferred embodiment of my improvements, it will be readilyunderstood that the precise details thereof may be varied withoutdeparting from the spirit of the invention.

It will be observed that in the periphery of the hub B are several holesI)", caused by the withdrawal of the pins which serve to sustain thesand core during the operation of casting the hub. These holes may besubsequently plugged up, or may be stopped, as shown in the drawings, bymeans of small lead caps 8, held in place by the pressure thereon of theinner ends of the Wooden segments.

I am well aware of the construction of lubricating devices illustratedin Letters Patent No. 256,841, granted April 25, 1882, and No. 293,070,granted February 5, 1884, and I wish it distinctly understood that Imake no claim to the features of construction of invention set forth insaid patents.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, with a body of a carwheel, of a hub formed separatetherefrom, said hub consisting of a perforated annular bearing-plate,I)", an annular chamber, G, for lubricant, the walls whereof are formedintegral with said beaiingplate, said chamber surrounding saidbearing-plate and being provided with the division-plates 9, extendingentirely across said chamber and having openings g therein to formareceptacle, G, for cot ton waste orlike material, said division-platesbeing located at each side of the perforation through the annularbearing-plate, whereby the cotton waste may be securely retainedseparate from the lubricatingchamber and abovethe opening of thebearing-plate, substantially as described.

2. The combination, with a body of a carwheel, of a hub formed separatetherefrom and having its periphery provided with suitable fianges, andhaving formed integral with said flanges aperforated annularbearing-plate for the caraxle journal, a closed chamber for lubricantsurrounding said bearing-plate and having its walls formed integraltherewith, said closed chamber being provided with the division-plates9, having openings 9, to form a cotton-waste receptacle opposite theperforation of said bearing-plate, substantially as described.
